Class Phalcon\Config

implements ArrayAccess, Countable

Phalcon\Config is designed to simplify the access to, and the use of, configuration data within applications. It provides a nested object property based user interface for accessing this configuration data within application code.

  1. <?php
  3. $config = new \Phalcon\Config(array(
  4.     "database" => array(
  5.             "adapter" => "Mysql",
  6.             "host" => "localhost",
  7.             "username" => "scott",
  8.             "password" => "cheetah",
  9.             "dbname" => "test_db"
  10.     ),
  11.     "phalcon" => array(
  12.             "controllersDir" => "../app/controllers/",
  13.             "modelsDir" => "../app/models/",
  14.             "viewsDir" => "../app/views/"
  15.     )
  16.  ));
